DCC via Netburner - that's pretty cool.

I have some NANO54415s that sometime don't boot when first powered up. If I pull the power cord from the carrier board and plug them back in, they boot fine. Power is coming from a 120vAC to 12vDC power brick, then to a 3.3v DC:DC regulator. I suspect the fraction of a second it takes the capacitors...

Shipping from China to the US is usually 2-4 weeks. If your biggest objection is the time delay, just buy one now and forget about the project for a month. Then you'll have the part when your interest comes back to this.

Two packet captures are attached below. Looks like the difference is that on the "slow" capture, I don't get a packet containing the 'HTTP/1.0 200 OK" to close the session. I'm using NNDK 2.7.3. I still have a lot to learn about C/C++, so I'll dig in to what malloc is and why it is ba...

How about a simple program that that can reproduce the issue. This app has a character array that gets filled by 1 byte every time the AJAX page is called. It goes good until it gets to about 750 bytes, then gets slow. Tested on two Nano modules, and in both Chrome and Firefox. I also noticed with t...

Chrome with the developer tools turned on shows that the page consistently takes 45 seconds to load. The content is returned immediately, but it appears there is a timeout somewhere of 45 seconds before it knows it is finished.

I have an app that uses AJAX to display a table of data in a web browser. The page is set for a refresh every 200ms. I have noticed that sometimes it is fast, sometimes it is really slow (2-30 seconds between updates in the browser). I added a simple iprintf("#"); to the function that gene...

I installed with 3 serial numbers, PK70, NANO54415, and MOD5441x. Of the three only the PK70 files were installed. All three serial numbers are listed in the serial_numbers.txt file, but there is a blank line after the PK70, which there isn't in the 2.7.1 version of that file. I also noticed that th...

That's correct, you need two boards for communication. Any device sending a message on a CAN bus has a spot at the end of the message for remote nodes to acknowledge that the message was received. If the sender doesn't see the message ACK'd, it knows that the message wasn't received by anyone. In my...
